https://pi.dev/ seems popular, whats not open source about opencode? The repo has an MIT License.
Some people believe only copyleft licenses are open source. They're right on principle, wrong in (legal) practice.
Maybe it's just my feeling. It asks to update/upgrade continuously.
Been LOVING Pi so far!
+1 for pi. I used claude and opencode but pi is the first agent tool that made me excited about the whole thing.
